Answer:
87 ft/sec
Step-by-step explanation:
mile/hr * hr/ seconds * feet/mile = feet per second
( see how 'mile' and 'hr' cancel out and you are left with feet/sec ?)
Now, put in the numbers :
59 * 1/3600 * 5280 = 86.533 = 87 ft/sec
im 68inches tall so how much is that into feet?
Answer:
5.68 ft
Step-by-step explanation:
12 inches = 1 feet
\(68 \: inches \: *\: \frac{1 feet}{12 \: inches} =\frac{68}{12} \: feet= 5.6777...\\\\68 \: inches \approx 5.68 \: feet\)
Parallelogram ABCD is rotated to create image A'B'C'D'.
The transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).
The rule that describes the transformation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).
To understand this, let's apply the transformation rule to each vertex of the original parallelogram ABCD:
Point A (2, 5) becomes A' (-5, 2).
Point B (5, 4) becomes B' (-4, 5).
Point C (5, 2) becomes C' (-2, 5).
Point D (2, 3) becomes D' (-3, 2).
By applying the transformation rule, we observe that the x-coordinate of each point becomes the negative of the original y-coordinate, and the y-coordinate becomes the original x-coordinate.
This transformation is a 90-degree counterclockwise rotation about the origin (0, 0) on the coordinate plane. The image parallelogram A'B'C'D' is obtained by rotating the original parallelogram ABCD by 90 degrees counterclockwise.
Visually, this transformation can be seen as the original parallelogram being rotated around the origin, where the x-axis becomes the y-axis, and the y-axis becomes the negative x-axis.
Therefore, the transformation rule that describes the rotation from the original parallelogram ABCD to the image parallelogram A'B'C'D' is (x, y) → (–y, x).

Please give the proof process: 2n3 + 3n +10 = Q( n³).
2n^3 + 3n + 10 can be written as a polynomial of the form Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3).
To prove that the expression 2n^3 + 3n + 10 is in the set Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3), we need to show that the expression can be written in the form a(n^3) for some constant "a".
Let's start by factoring out the common factor of n^3 from each term:
2n^3 + 3n + 10 = n^3(2 + 3/n^2 + 10/n^3)
Now, let's rewrite the expression as a single term multiplied by n^3:
2n^3 + 3n + 10 = (2 + 3/n^2 + 10/n^3)n^3
Simplifying the expression inside the parentheses:
= (2n^3 + 3n^2 + 10n^3)/n^3
= (12n^3 + 3n^2)/n^3
= 12 + 3/n
ow, we can see that the expression can be written in the form a(n^3), where a = 12 and n^3 = 3/n.
Therefore, we have shown that 2n^3 + 3n + 10 can be written as a polynomial of the form Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3).

what is the rule multiplying with different signs
Answer:
When you multiply two numbers with different signs (positive and negative), the result is always negative.
This can be understood in terms of the basic properties of multiplication and the fact that a negative number is essentially the opposite of a positive number. When you multiply a positive number by a positive number, the result is positive because both numbers are pointing in the same direction along the number line. When you multiply a negative number by a negative number, the result is also positive because both numbers are pointing in the opposite direction along the number line, and multiplying them together "flips" them back to the positive side. However, when you multiply a positive number by a negative number, the two numbers are pointing in opposite directions along the number line, and so their product is negative.
Therefore, the rule for multiplying two numbers with different signs is that the product is always negative.

carlos es un arquitecto y esta construyendo una casa si ha construido 3/7 de la casa le falta para acabarla es lo mismo que llegar a 7/7
Answer:
Ok, sabemos que Carlos ha construido un 3/7 de una casa.
Queremos saber cuanto le falta para terminar de construirla.
Entonces podemos realizar el cálculo:
1 casa - lo que Carlos ya construyo = Lo que le falta.
Entonces:
1 casa - 3/7 de una casa = X
Podemos reescribir:
1 casa = 7/7 de una casas
así tenemos:
7/7 de una casa - 3/7 de una casa = X
(7/7 - 3/7) de una casa = X
4/7 de una casa = X
Así podemos concluir que a Carlos le falta construir 4/7 de una casa para acabar.
use the ti-84 plus calculator to find the z-scores that bound the middle 96% of the area under the standard normal curve. enter the answers in ascending order and round to two decimal places.
The Ti-84 Plus calculator can be used to find the z-scores that bound the middle 96% of the area under the standard normal curve. The z-scores should be entered in ascending order and rounded to two decimal places.
To calculate the z-scores, we need to find the boundaries that enclose the middle 96% of the area under the standard normal curve. Since the standard normal curve has a total area of 1, the remaining 4% is divided equally into two tails, each containing 2%. To find the z-scores corresponding to these boundaries, we can use the inverse normal distribution function on the Ti-84 Plus calculator.
Using the inverse normal distribution function, we can find the z-score that corresponds to a cumulative probability of 0.02 (2% on one tail). This z-score represents the lower boundary. Similarly, we can find the z-score corresponding to a cumulative probability of 0.98 (2% on the other tail), which represents the upper boundary.
By entering these z-scores in ascending order and rounding them to two decimal places, we can determine the z-scores that bound the middle 96% of the area under the standard normal curve using the Ti-84 Plus calculator.

what is the probability that a three digit number is divisible by 7?
The probability that a three- number integer is separable by 7 is 3/20or 0.15.
To determine the probability that a three- number number is separable by 7, we need to count the number of three- number integers that are separable by 7 and also divide that number by the total number of three- number integers.
First, we need to find the lowest three- number integer that's separable by 7. We know that 14 is the lowest two- number integer separable by 7, so the lowest three- number integer that's separable by 7 will be the coming multiple of 7, which is 105.
Next, we need to find the largest three- number integer that's separable by 7. The largest three- number integer is 999, and the largest multiple of 7 that's lower than or equal to 999 is 994. So, we need to count the number of integers that are separable by 7 between 105 and 994.
We can do this by using the formula for the number of integers in an computation sequence
number of integers = ( last term-first term)/ common difference
In this case, the first term is 105, the last term is 994, and the common difference is 7, so we have
number of integers = ( 994- 105)/ 7 1 = 135
Thus, there are 135 three- number integers that are separable by 7.
The total number of three- number integers is 900( from 100 to 999). So, the probability that a three- number integer is separable by 7 is probability = number of integers that are separable by 7/ total number of three- number integers probability
= 135/ 900 probability = 3/ 20

How do you simplify a binomial by a binomial?.
One binomial's terms are multiplied by the other binomial's terms. The algebraic total of these products is then calculated after this step. We employ a technique called the FOIL method to multiply binomials.
Therefore, the order in which the terms are multiplied in this order is FOIL (First Outer Inner Last).
An algebraic expression with two terms joined by a plus or minus sign is known as a binomial. Binomial multiplication is comparable to multiplying two whole numbers or fractions. Utilising the distributive property of multiplication twice is one way to multiply binomials.
The letters in the acronym FOIL stand for First, Outer, Inner, and Last. Since only binomials may be multiplied using this approach, it cannot be used to multiply all polynomials. The FOIL formula has the following general form: (a + b) (c + d) = ac + ad + bc + bd.

One hundred fifty tickets are sold for 20 per ticket. The four winning prizes are 300, 150, and two 50 prizes.
We can see here that expected value per ticket is: $4.34
What is expected value of raffle ticket?The average sum of money that a purchaser of a raffle ticket may anticipate winning is known as the expected value of a ticket. It is computed by multiplying the likelihood of each award by its value in money, adding all the results, and then computing the result.
The total amount of money collected from selling tickets:
Total amount collected = Number of tickets sold × Price per ticket
Total amount collected = 150 × $20 = $3000
Expected value = (Probability of winning) × (Value of the prize).
$300 prize:
Probability of winning = 1 / Total number of tickets = 1 / 150
Expected value for $300 prize = (1 / 150) × $300 = $2
$150 prize:
Probability of winning = 1 / Total number of tickets = 1 / 150
Expected value for $150 prize = (1 / 150) × $150 = $1
Two $50 prizes:
Probability of winning = 2 / Total number of tickets = 2 / 150
Expected value for each $50 prize = (2 / 150) × $50 = $0.67.
Total expected value per ticket = Expected value for $300 prize + Expected value for $150 prize + 2 × Expected value for $50 prize
Total expected value per ticket = $2 + $1 + (2 × $0.67) = $2 + $1 + $1.34 = $4.34

3y + 15 = 2x + 15 =
Answer:
x = 3/2y
y = 2/3x
Step-by-step explanation:
x = 3/2y
Swap sides so that all variable terms are on the left hand side
2x + 15 = 3y + 15
Subtract 15 from both sides
2x = 3y + 15 - 15
Subtract 15 from 15 to get 0
2x = 3y
Divide both sides by 2
2x/2= 3y/2
Dividing by 2 undoes the multiplication by 2
X = 3y/2
Y = 2/3x
Subtract 15 from both sides
3y = 2x + 15 - 15
Subtract 15 from 15 to get 0
3y = 2x
Divide both sides by 3
3/3y = 2/3x
Dividing by 3 undoes the multiplication by 3
y = 2/3x

For the molecule on the left with a bromine atom, the highest priority group is the bromine atom which is to the right, the lowest priority group is the hydrogen atom which is behind the plane, and the remaining two groups, carbon and chlorine, are on the same side of the plane.
The orientation of the remaining two groups is such that the lower priority atom is behind the plane, and we move from the highest to the lowest priority in the clockwise direction, so the stereochemistry is R. For the molecule on the right with a chlorine atom, the highest priority group is the chlorine atom which is to the left, the lowest priority group is the hydrogen atom which is behind the plane, and the remaining two groups, carbon and bromine, are on the same side of the plane. The orientation of the remaining two groups is such that the lower priority atom is behind the plane, and we move from the highest to the lowest priority in the clockwise direction, so the stereochemistry is R.
Both the molecules are diastereomers because they have different configurations at both stereocenters. Diastereomers are a type of stereoisomers that are not enantiomers. Diastereomers are stereoisomers of a molecule that have different configurations at one or more chiral centers and are not mirror images of each other.

Consider the following macroeconomic model: Y = C + 1* + G* + X* – M* (equilibrium of national income) C = a(Y – T) + b (consumption; 00) T = tY (taxation; 0
This macroeconomic model illustrates how changes in different factors (consumption, investment, government spending, exports, and imports) and their relationships with income can impact the equilibrium level of national income.
Based on the given equations, Y represents the equilibrium level of national income, which is determined by the levels of consumption (C), investment (I), government spending (G), exports (X), and imports (M).
The consumption equation, C, is dependent on disposable income (Y-T), where a represents the marginal propensity to consume (MPC) and b represents autonomous consumption. This means that as disposable income increases, consumption will increase, but at a decreasing rate due to the MPC. Autonomous consumption, on the other hand, is independent of income and reflects the amount of consumption that would still occur even if income were zero.
The tax equation, T, shows that taxes are a function of income (Y), where t represents the tax rate. As income increases, taxes will also increase proportionally.
Overall, this macroeconomic model illustrates how changes in different factors (consumption, investment, government spending, exports, and imports) and their relationships with income can impact the equilibrium level of national income.
